To solve the equation \( x + 3.8 = 8.7 \) using inverse operations, we need to isolate \( x \).
1. Start with the equation:
\[
x + 3.8 = 8.7
\]
2. To isolate \( x \), subtract \( 3.8 \) from both sides of the equation:
\[
x + 3.8 - 3.8 = 8.7 - 3.8
\]
3. Simplifying both sides gives:
\[
x = 8.7 - 3.8
\]
4. Now, perform the subtraction:
\[
8.7 - 3.8 = 4.9
\]
Therefore, \( x = 4.9 \).
Chloe threw her first ball **4.9 meters**.
1. Start with the equation:
\[
x + 3.8 = 8.7
\]
2. To isolate \( x \), subtract \( 3.8 \) from both sides of the equation:
\[
x + 3.8 - 3.8 = 8.7 - 3.8
\]
3. Simplifying both sides gives:
\[
x = 8.7 - 3.8
\]
4. Now, perform the subtraction:
\[
8.7 - 3.8 = 4.9
\]
Therefore, \( x = 4.9 \).
Chloe threw her first ball **4.9 meters**.
